To all whom t may concern j Be it known that l, Harvey ELLIS .Wanna acitizen of the United States, residing at Denver, in the county ofDenver and State of Colorado, have invented a new and useful Carbureter,of which the following is a specification.

The present invention. appertains to carb'ureters, and aims to provide anovel and improved apparatus of that character.

lt is the object of the invention to provide a carbureter of novel andimproved construction ior the production of carbureted air, which can beused generally for lighting and heating purposes, the present gas. beingproduced artificially by the passage of air under pressure throughgasolene or other volatile hydrocarbon.

It is also within the scope of the invenac tion to provide a carbureterof the nature indicated which is comparatively simple and inexpensive inconstruction, as well as being practical and eiiicient in use.

With the foregoing and other objects in a5 view which will appear as thedescription proceeds, the invention resides in the 'combination andarrangement of parts and in 1 the details of construction hereinafterdescribed and claimed, ,it being .understood 3c that changes intheprecise embodimentv of the invention herein disclosed can be made withinthescope oi. what is claimed without departing from the spirit of theinvention.

The invention is illustrated in the accom panying drawings, whereinFigure 1 is a side elevation of the apparatus. Figs. 2 and 3 arevertical sections taken on the lines 2-2 and 3-3, respectively, of Fig.l. Fig. 4 is a sectional detail taken on the line 1l-44 of Fig. '3. v

In carrying out the invention, there is employed a pair of uprightcylindrical tanks 1-2 set on-end adjacent one another. These tanks arepreferably constructed of sheet e5' metal and have the convened heads 3and bottoms 4. Each tank is also provided therein between its upper andlowernds with a horizontal sheet metal partition yhaving its marginriveted' or `otherwise secured to the side vaall's ofthe tank. i

' I Bisposed wifhin'each tankabove the partition 5 thereof is a. hood 6,preferably constructed of sheet metal, and having its rim or lower endseating upon the partition 5.

The hood 6`is oi'I slightly smaller diameter than the tank to provide anannular space therebetween, and angular spacing members 7 are riveted orotherwise secured to the rim of the hood adjacent the lower end thereofand project outwardly to Contact with the tank for spacing the hoodtherefrom. Angle members 8 are riveted or otherwise securedV to the tankand project over and Contact with the upper end of the hood lfor holdingthe hood seated. .upon the partition. The hood 6 has annular'series ofapertures establishing communication between the in.

terior of the 'hood and the annular space between the hood and tank. Thehood 0i.:-

tank l has only lower apertures 9. Thus, the liquid level. within thehood 6 of tank 1 will be lower than the liquid level 'within thehood oftank t2.. This shows how the hoods( can be provided with apertures atdiiierent points thereof, according to the circumstances.

A vertical pipe or conduit 10 is engaged centrally through eachpartition 5 axially or concentrically within the respective tank, sothat the upper end of the pipe 1G projects within the hood 6, while thelower end depends from the partition 5. The lower end of the pipe l0 isprovidedwith a dared mouth 11, and the pipe 10 has an annular series ofapertures l0 immediately above the partition 5.

Patent-ea nec. ce, ieee..l

Within each tank, there isV an air chamber 'l2- below the partition 5and above the lower end oi2 the pipe 10, a second air chamber 13 vwithinthe upper portion of the hood 6 above the upper apertures 9, and a thirdair chamber 14 within the upper portion 'of the tank abovethe hood.l A.pressure gage 15 is attached to each tankin communication with thevchamber 1 4 to indi cate the pressure of the gasqvithin said chamber.

Each tank is provided with diametrically opposite vertical by-pass pipes16 having 1 i their ends attached to the respective walls ot the tankadjacent the bottom 4 thereof tank 1 adjacent the bottom thereof and be.

low the chamber'12,by anv airsupply pipe 21 extending to an aircompressor (not shown) engaged through one Iwall 'of the tank 1 adjacentthe bottom of said tank. The pipe 21 is provided with a pressure orescape valve 22 having an outlet branch 23, whereby when the airpressure exceeds the desired amount, the surplus air is let out throughthe branch 23 to the atmosphere. rlhis prevents an eXn cessive pressureof the air and gas. The pipe 21 is also provided with a check valve 24-adjacent the tank 1, to allow the air to flow into the tank, but toprevent the retrograde flow of the air and liquid from the tank.

`lhe pipe 21 also has a controlling valve 25.

`W ith the tank 1, the pipe 21 has acruciform air outlet member 26embodying the radial tubular arms 26 attached to a coupling 26a which inturn is attached to the end of the pipe 21, the outer ends of the arms26 being closed by caps 26". The outlet member 26 has upper apertures. I

The upper end of the tank 1 is provided with outlet means whichcommunicate with the lower end of the second tank 2, and to this end,the head 3 of the tank 1 is provided with rliarnetrically oppositeupstanding out let pipes 27 which have secured thereon the couplings28-29- The coupling28 is a T- coupling whereas the coupling 29 is acruci- Y form or Eli-shaped coupling provided with a removable closureplug 30 which can be removed for allowing the tank to be filled withgasolene or other volatile hydrocarbon. ".lhe

couplings 28-29 are connected by an equal-v izing pipe 31, and saidcouplings `have attached thereto, the upper ends'of a pair` of oppositeinclined pipes 32 which have their lower ends connected to diametricallyopposite walls of the tank 2'adjacent the bottom l thereof. The gas inthe chamber 14 of the tank 1 therefore flows into the lower portion oflthe second tank 2 by way of the' pipes 32.

The upper end of the tank 2 is provided with a ges outlet embodying acoupling 33 attached to the upper end of the said tank, and the gas mainor pipe 34; is connected to the coupling 33. The c upling 33 has aremovable plug 35 which when removed allows the gasolene or volatilehydrocarbon to be poured into the tank`2.

ln operation, the tanks are rst filled with the gasolene or othervolatile hydrocarbon, which will lill the tanks as indicated in l Figs.2 and 3. vThe liquid will fill the lower portion of the, tanks up to orslightly above f the lower ends of the pipes 10, which provides theconfined air or gus chambers 12, and the liquid will also till the hoods6 up to or slightly above the upper apertures 9 thereof. the partition 5preventing the liquid from flowing directly downward. r-`he liquid alsofills the tank outside of the hoods il. The pressure of air trulipedwithin the various chambers prevents the indou' of hacerse liquidther-cinto above the liqui'dentrance openings, except to such aldistance as the volume of trapped air may be reduced due to the externalliquid pressure head. The pipes 10 provide means of communicationbetween the liquid in the lower ends of the tanks and the chambers 13,and the aperf.

tures 9 establish communication between the liquid in the hoods 6 andthe chambers 14,

-the air or gas in` being forced from one chamberto the other beingcompelled to low through the liquid whereby the air willv I becomesaturated with the volatile liquid,t o produce the carbureted air whichmaybe yused for lighting and heating purposes generally, for runninginternal explosion vengines, and the like. through the pipe 21 from asuitable compressor (not shown) and is forced through lthe apertures ofthe member 26 into the liquid within the lower portion of the tank Theair isliorced 1. The air then rises through the liquid into the lowerend ofthe respective pipe 10 and up through said pipe into therespective chambery 13. From the chamber 13, the air is forced throughthe apertures 9 and y lates in the upper chamber 14 of the tank 2 i andis then discharged into the gas main or pipe 34 by which it is led tothe point of consumption;

The valves 17 whenv opened 'v permit the liquid to flow through thelay-pass pipes 16, whereby the liquid may liow past the partitions 5more readily. The valves 19 are ordinarily closed and when the caps 20are removed, the-valves 19 can be opened for draining the tanks, andfurthermore, when an oil or heavier hydrocarbon is used, the same may beforced into the tanks by way of the branches 18 and pipes 16.Itis'evident7 also, in the operation of the device that the air willflow Jfrom the pipes 10 through the apertures 10 into the liquid withinthe hoods 6. rlhe superposed liquid chambers ,of each tank are incommunication, whereby they liquid can How from the upper liquid chambertothe lowermost. and there is a gas chamber above each liquid chamber.

The two tanks are practical duplicates of one another, with slightvariations, and in some cases but a y`single tankneed be used, and ifdesired more than two tankscan be connected in series. y

rthe compressor which is used for projecting the compressed air into thetanks, canfsoa'es aocm'ng to *the use to which ii; is put, and can beuse eihel' fof omestic pm"- poses or asn oonmlercal pzm.
